IMPROVEMENT IN CORN-PLOWS.

Specification forming part of Letters Patent N0. 35,434, dated June 3,1862.

To all whom it may concern:

Be it known that I, WILLIAM B. BROAD- WELL, of Springfield, in thecounty of Sangamon and State of Illinois, have invented a new andImproved Corn-Plow; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being bad tothe accompanying drawings; making a part of this specification, inwhich- Figure l is a side view of my invention. Fig. 2 is a plan or topview of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it. A A represent two horizontalbeams, to the back parts of which two .inclined bars, B B, are attachedby a short horizontal cross-piece, G.

The bars B B are parallel with each other, and; 1

they form plow-standards, an ordinary shovel,

share, or plow, D, being attached to the lower end of each standard. Onestandard of each beam is a little in advance of the other, as shownclearly in Fig. 2; and to the inner standard of each beam there isattached a handle, E, through which and the upper parts of the outermoststandards, B B, a bar, F, passes, as shown in Fig. 2.

Gr is a bar, which is secured to the innermost standards, B, by means ofmetal clamps H,

which are formed of a U-shaped rod, having screw-threads cut on theirends, on which a cross-baiya, is fitted, and nuts to" a, as'shownclearly in both figures. This bar G connects the two parts of the plowtogether, as clearly shown in Fig. 2, and one part only of the plow maybe used, when desired, by simply detaching bar G. This bar G may beadjusted at any proper height on the innermost standards, B, so that itmay clear the plants as the implement is drawn along.

The cross-pieces G Gare ofsuch a length as to admit of the plowsor'shares D being a proper distance apart;

Between the two parts of the implement there is attached a lender orguard, I, which is formed of two parts, composed each of a series ofparallel rods, a, the ends of which are fitted in bars I), inclined soas to give the two parts a flaring position, their lower edges beingfarther apart than their upper edges. The back bars b are securedcentrally to the bar G by a bolt, 0, and the front bars I) are securedto rods d d, by which they are connected to the beams A A. The frontbars I) are farther apart than the back ones, and have a lower position,so as to give the fender or guard a requisite degree of inclination, asshown in Fig. 1. This tender or guard prevents clods of earth beingthrown on the plants by the action of the plows or shares, the fender orguard being over the tops of the plants and extending down at each sideof them. The plows or shares of the innermost standards, B B, work nearthe row of plants, one at each side of them, and they may be adjustednearer together or farther apart, as may he required, by means of bar G.

The fender or guard I may be detached from the machine at any time whennot required-- as during the second plowing of corn, for instance.

Thus it will be seen that one or both parts of the plow may be used asdesired, and the implement consequently adapted for one or two horses,while the expense of construction will not exceed that of ordinarycultivators.

I do not claim separately any of the parts 7 described but I do claim asnew and desire to secure by Letters Patent- In combination with the barG and clamps H H, the fender or guard I, applied to the beams A A andbar G, as and'for the purpose specified.
